💡 Running Tips

80/20 Rule

Elite runners do 80% of training at easy pace (Zone 1-2) and only 20% at high intensity. Most recreational runners do too much at moderate pace.

Negative Splits

Running the second half of a race faster than the first is the optimal strategy for most runners. Start conservatively.
